CAR-WHEEL.

SPECIFICATION forming part of Letters Patent No. 366,180, dated July 5, 1887. Application filed August 4, 1886. Serial No. 209,942. (No model.)

To all whom it may concern.-

Be it known that I, EDGAR PEOKHAM, of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Oar-\Vheels, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to the class of carwheels which are partly composed of paper interposed between the hub and tread of the wheel, so as to relieve the wheel from jars and render the same noiseless.

The invention consists in an improved construction and combination of parts, as hereinafter fully described, and set forth in the claims.

In the annexed drawings, Figure 1 is a side elevationof my improved car-wheel. Fig. 2 is a transverse section of the same. Fig. 3 is a detached rear side view of the wheel-body. Fig. 4 is a front view of the wheel-hub bare of all the detachable parts of the wheel. Fig. 5 is a detached plan View of the tire-retaining ring. Fig. 6 is a detached plan view of the outer ring of the wheel-body. Fig. 7 is adetached side view of the hub, and Fig. Sis a detached face view of the collar by which th wheel-body is retained on the hub.

Similar letters of reference indicate corre sponding parts.

A denotes a car-axle, and H the wheel-hub,

rigidly secured on said axle in any ordinary and well-known manner. Said hub is formed at one end with a stout wide flange, F, which has on its inner side an overhanging projection, f, from which extend lugs h part way toward the hub, for the purpose hereinafter explained. The opposite end of the hub is provided with a diagonal groove, 0, extending through theend of the hub, and in this groove is locked the collar I, which is provided with lugs m, projecting into the eye of the collar, as represented in Fig. 8 of the drawings, and adapted to enter the groove 0, said collar being slipped onto the hub by entering the lugsor into said grooves from the outer ends thereof, and in pushing the collar along on the hub the lugs follow the grooves and finally become wedged therein by the resistance of the abutment of the collar against the side of the wheelbody. By means of bolts (1 d, passing throughthe collar I, flange F, and intervening wheelbody, the aforesaid collar is retained in place. The collar I is formed on the side facing the flange F with an overhanging projection, i, as illustrated in Fig. 2 of the drawings.

Between the flange F and collar I is secured the body of the wheel, which is constructed as follows: A ring, C, is inserted between the outer peripheral portions of two annular steel plates, P P, which are secured to opposite sides of said ring in the manner hereinafter described. Said plates are each provided with a central eye of somewhat greater diameter than the wheel-hub, which passes through said eye. The ring G, with the plates P P attached thereto, as aforesaid, forms a hollow metallic body, the cavity of which extends to the central eye of the body, and this cavity I fill with a core, D, of compressed paper or analogous elastic material.

The core is made to project over the eye of the described metallic body, and has a central eye of the same diameter as the hub H, so as to have a firm bearing thereon and support the metallic body isolated from the hub, thus insuring the elasticity to the axial support of the wheel derived from the interposition of the paper core between the outer ring, 0, and hub.

The plate I? on the inner side of the wheel I form with a bulge around the hub, as shown in Fig. 2 of the drawings, the said bulge bringing the bearing of said plate on the hub in a line extending from the flange of the wheel to the hub at right angles to the axis of the latter, and causing the outer peripheral portion of said plate to be deflected outward, and thus brace the wheel against thestrain received by the pressure of the flange against the side of the track-rail. At thesame time the aforesaid bulge of the inner plate, P, enlarges the cavity between it and the other plate, 1 around the hub, so that the non-metallic core D, which is bulged correspondingly, receives a. broader bearing on the hub, and said cavity and core are tapered toward their outer peripheries, and thus the core iswedged in the cavity between the plates 1? P, so that the radial strain on the wheel exerts side compression on the core.

To the exterior of the plates P P,around the eyes thereof, are rigidly secured re-enforcing plates 19 p, which occupy the recesses formed on the inner sides of the flange F and collar I by the overhanging projections f z, hereinbefore described.

' The platep is provided in its outer periphery with notches a n, coinciding with the lugs 72. h, which project from the flange portion f toward the hub, as hereinbefore explained. The engagement of said lugs with the notches a it forms a clutch, which compels the hub to rotate with the body of the wheel, and thus relieves the bolts d iirom shearing strain, said bolts passing through the collar I, plates P P,

intervening core, D, and flange F, and serve to clamp the-collar I firmly against the side of the wheel-body and confine the latter on the hub.

T represents the steel tire, which I form at one edge of its inner peripheral face with an undercut inwardly-projecting flange, t, and at the opposite edge of said face with an undercut circumferential groove, a. This tire I secure to the body of the wheel by forming the ring 0 with a laterally-projecting circumferential flange, a, on the outer edge of one side, which flange interlocks with the flange tof the tire, as represented in Fig. 2 of the drawings.

The .outer periphery of the plate P is flush with that of the ring O, and thus has a direct bearing on the tire T, which bearing relieves the bolts 6 e from shearing strain.

The entrance to the groove a is sufficiently wide to receive two rings, R and B, side by side. The outer ring, R, is formed with a laterally-projecting flange, b, which enters the undercut portion of the groove a, and thus be comes interlocked with the overhanging portion of the tire, and the other ring, R, is plain and introduced between the ring R and ring 0, as shown in Fig. 2 of the drawings.

The ring R is composed of two segments and a key, is, introduced between the ends of said segments, and the ring R is formed likewise in this respect, so as to permit of introducing said rings into the groove a. The key of the ring R is provided with an eye, 14;, and the key of the ring It has projecting from its side a lug, 0, which protrudes through the eye w and through a coinciding eye, w, in the clamp U, which is placed on the exterior of the key 7c of the ring R and laps onto the ends of the sections of said ring. By means of bolts 0 e, passing through the clamp U, rings R R,

plates P P, and ring (3, said parts are firmly united.

It will be observed that,by the projection of the flange u 011 one side of the'ring O and the flush edge of the plate P on the opposite side of said ring, the body of the wheel receives a broad bearing-surface on the tire, and thus properly sustains the same, and by the abutment of the periphery of the plate 1? against the overhanging portion of the flanget the latshown and described.

ing from the sides thereof and through corre- 1 sponding perforations in the plates P P, as-

shown in Fig. 20f the drawings.

I do not hereby claim, broadly, a car-wheel composed of a central body, a tire formed on its inner peripheral face with shoulders or flanges at opposite sides of the aforesaid body, and a retaining-ring inserted between one of said shoulders and adjacent side of the body,

such a combination of parts being shown in other applications for Letters Patent filed by me August 2, 1886; but i What I claim as new, and desire to secure by Letters Patent, is-

1. A car-wheel composed of a hub, an outer ring, plates secured to the opposite sides of said ring and to a hub, a non-metallic core filling the cavity between the aforesaid plates and seated directly upon the hub, and a tire secured to the outer ring, substantially as of an outer ring, plates secured to opposite sides of said outer ring, and a non-metallic core filling said cavity between said plates, said cavity being enlarged by a bulge of the inner side plate around the central eye thereof and the non-metallic core enlarged correspondingly, whereby an enlarged bearing for said core is secured upon the hub, substantially as described and shown.

3. The combination, with the hub and hollow metallic body, of a non metallic "core seated directly on the hub, and clutch-connections between the hub and metallic body to compel the latter, together with the core, to rotate with the hub, substantially as set forth and shown.

4.. In a car-wheel, the combinatiomwith the hub, of a metallic wheel-body having an internal cavity extending to the central eye of said body and a core of paper or analogous elastic material in said cavity, said core projecting over the central eye of the wheelbody to bear on the hub and sustain the eye of the metallic body isolated from the hub, substantially as and for the purposes set forth.

5. The combination, with the hub, of the annular metallic plates PP, having central eyes of greater diameter than the hub, the ring 0, secured between the peripheral portions .of said plates, and the core D, of paper or analogous material, filling the cavity between the plates and having a central eye of the same diameter as the hub, substantially as described and shown.
